Cambridge, Massachusetts – October 24, 2026 -- Harvard University researchers reported control of more than 3,000 neutral atom qubits, one of the largest experimental quantum systems to date, in a paper published in Physical Review Letters.

The work demonstrates long-coherence control and advances the pursuit of fault-tolerant quantum architectures.

Kawasaki, Japan – September 11, 2026 -- Fujitsu has developed the world's first working prototype of a diamond-spin quantum computer that integrates tin-vacancy (SnV) centers into photonic integrated circuits, a milestone the company says advances the path toward scalable quantum systems.
